@FighterPilot Why don't people get it i don't really understand its simply thing combining mate billion times asked :D Ill tell it just pick a one dlc like this one CTSVC is the Base dlc then in desktop create a new folder then open like DBS08 DLC then in x64/vehicles export dbs08 ytd and yft's in new folder then open data folder than extract carvariations vehicles and handling data in new folder then open CTSVC DLC then open x64/vehicles.rpf then import dbs08_hi.yft dbs08.yft and dbs08.ytd then open data folder and right click to edit carvariation.meta then in new folder you exported carvariations.meta open it then copy started point <item> <modelname> to ..... <sirenssettings blabla> </item> then paste it to right clicked carvariations meta under the <variationdata> upper the <item> then use same way to handling and vehicles meta too and done you add the dbs in ctsvc so that way 180-240 vehicles you can put in 1 dlc dlc size is important over 4.1 gb makes game crash

@F7YO Oh wow! I really thankyou for taking time to explain to me the procedure step by step!!
As i'm new to this converting independent mods to dlcs, i guess it'l take time for me to get it to work correctly :D
Btw is there any short tutorial or explanation video showing how to do it?
